To all whom it may concern:

Be it known that we, Cnennns R. Harms and Lownnr. .W. Lyons, citizens of the United States, residing at Los Angeles, in

the county of Los Angeles and State of California, have invented certain new and useful Improvementsin Roller-Bearings, of which the following is a specification.

@ur invention relates to an improvement it in roller-bearings of the type in which the rollers are all of uniform length, whether main rollers or idiots, in connection with other features, in which the friction due to end thrust is reduced to a it In the accompanying drawings Figure 1 is a longitudinal section on th line aV-e' oi Fig. 2; Fig. 2 is a transverse section on the line w -m of Fig. 1; and at Fig. 3 is a transverse section on the line se -4v of Fig. 1.

The numeral 1 represents a flange or collar screwed or held by friction, as preferred, as shown in Fig. 1, at the left and right ends upon the inner sleeve 8 of the bearing. These collars are provided with recesses 2 cut in the same to receive the reduced ends 4 of the bearing rollers 6 and 9, the extreme ends of which are rounded as at 5 to engage W the ends of the flanges or collars at a point, thus reducing the end thrust friction to a minimum. The roller-bearin are housed by an outer sleeve 3,,whic surrounds them, and the roller-bearings 6 are turned down and cut away at intermediate points, thus leaving the enlarged collars 7 at intervals, as shown in Fig. 1. v This reducing of the intermediate portions allows s ace for air 0 circulation to keep the rollercaring cool.

The collar 7 engages and turnson the inner sleeve 8 and against the surface or the straight rollers 9.

In addition to the collars or flanges 1' 15 being threaded 0r frictionally held in lace, one might be turned integral with the inner sleeve 8, if dmd.

Various other modifications might be made.

We claim:

1. A roller bearing comprising inner and outer sleeves and end flanges or collars, together with rollers of umform length, the ends of which are rounded or convex, whereby to engage recesses in the flanges or collars at a point,.thereby reducing friction to a minimum.

2. A roller bearing comprising inner and outer sleeves and end flanges or collars, to-

.gether with straight and collared rollers of;

uniform length, the ends of which are rounded or convex, whereby to engage recesses in the flanges or collars at a point, thereby reducing friction to a minimum.

3. A roller bearing comprising inner and outer sleeves and end flanges or collars, togather with rollers and idlers of uniform ength, the ends of which are rounded or convex, whereby to engage recesses in the flanges or collars at a point, thereby reducing friction to a minimum, the main portion of said rollers and idlers being of different diameters.

4. A roller bearing comprising inner and outer sleeves and end flanges or collars, together with rollers and idlers of uniform length, the ends of which are rounded or convex, whereby to engage recesses in the flanges or collars at a point, thereby reducing friction to a minimum, the main portion of said rollers and idlers being of different diameters, and the reduced ortions of said rollers and idlers having t e same diameters.

5. A roller-bearin comprising inner and outer sleeves and en flanges or collars having recesses on their inner faces, straight and collared rollers of uniform length the ends of which are rounded or oonvexed and received within said recess whereby they are held collectively together.

6. A roller-bearing comprising inner and outer sleeves and end flanges or collars,

having recesses in their inner faces, rollers anfl ilel 's of uniform length the enls of which are seduced in dlemeter and roundecl essee? convexed and received within said recesses whereby they are held collectively together, said outer sleeve of such a Width as to be a received between the inner face of said end flanges 01: collars.

In "testlmony whereof We affix our signatures.
